The necessity of a Freezer Condenser is based on the second law of thermodynamics. According to the second law of thermodynamics, the spontaneous flow direction of thermal energy inside a closed system is unidirectional, that is, it can only flow from high heat to low heat. In the microscopic world, it appears as microscopic particles that carry thermal energy. From order to disorder. Therefore, when a heat engine has energy input to perform work, it must also have energy release downstream, so that there will be a thermal energy gap between upstream and downstream, the flow of thermal energy will become possible, and the cycle will continue.

Therefore, if you want the load to perform work again, you must first release the heat energy that is not completely released. At this time, you need to use a condenser. If the surrounding heat energy is higher than the temperature in the condenser, artificial work must be done in order to cool the condenser. The condensed fluid returns to a state of high order and low heat energy and can perform work again.

The choice of condenser includes the choice of form and model and determines the flow and resistance of the cooling water or air flowing through the condenser. The choice of condenser type should consider the local water source, water temperature, climatic conditions, as well as the size of the total cooling capacity of the refrigeration system, and the layout requirements of the refrigeration machine room. On the premise of determining the condenser type, the heat transfer area of ​​the condenser is calculated according to the condensing load and the heat load per unit area of ​​the condenser, so as to select the specific condenser model.
